den Hartog, Dylan (author)Background: Osseointegration is a relatively new alternative for a socket to attach an artificial limb to the stump of an amputee. In a surgical procedure, a metal implant is permanently anchored and integrated into the bone of the stump. Amputees with an osseointegrated prosthesis have indicated that they experience better physical control over...master thesis 2021

Fransen, Stefan (author)This work investigates low-cost three-dimensional (3D) ultrasound reconstruction from a two-dimensional (2D) hand-held probe with motion tracking. The best available motion tracking is an optical tracking system, which is expensive and requires external tracking hardware. Here, a low-cost manoeuvrable motion tracker, an inertial measurement unit...master thesis 2021

de Kanter, Daan (author)Inertial Measurement Unit (IMU)-based motion capture has gained interest over the years due to its potential to measure human movement in the clinic and on the sports field at low cost. Still, IMU-based motion reconstruction remains a challenging task as these IMU measurements are corrupted by noise and bias. There have been many filtering and...master thesis 2021

Weygers, Ive (author), Kok, M. (author), Seel, Thomas (author), Shah, Darshan (author), Taylan, Orçun (author), Scheys, Lennart (author), Hallez, Hans (author), Claeys, Kurt (author)A major shortcoming in kinematic estimation using skin-attached inertial sensors is the alignment of sensor-embedded and segment-embedded coordinate systems. Only a correct alignment results in clinically relevant kinematics. Model-based inertial-sensor-to-bone alignment methods relate inertial sensor measurements with a model of the joint....journal article 2021

van Ingen, Bart (author)Pedestrian indoor localization is a problem yet to have a solution that is as generally accepted as the Global Positioning System is for outdoor localization. An infrastructure-independent option is to leverage the data from Inertial Measurement Unit (IMU) sensors to determine position. An advantage of this approach is that these sensors are...master thesis 2020

Edridge, Thomas (author)Higher-grade Inertial Measurement Units (IMUs) provide a better estimation of the orientation but are more expensive than lower-grade IMUs. The increase in availability and affordability of lower-grade IMUs over the last few years has provided an alternate solution: combine multiple lower-grade IMUs to increase sensor accuracy at low cost....master thesis 2020

Kaketsis, Georgios (author)The goal of this report is to present and describe the effort surrounding the completion of the Master Thesis Project of classification in football. Classification is a procedure which belongs in the field of Statistics. The objective is to capture, detect and distinguish certain actions relative to the environment of analysis. In our case we are...master thesis 2020

Boedhoe, Raoul (author)Total Hip Arthroplasty (THA) is a procedure where a defective hip joint with pain symptoms or functional impairment is replaced by a hip prosthesis. During this procedure, the optimal hip prosthesis should be chosen and placed in the correct orientation to achieve a stable hip joint. Failure to do so can lead to dislocation, mechanical failure...master thesis 2020

Girrbach, Fabian (author), Kok, M. (author), Zandbergen, Raymond (author), Hageman, Tijmen (author), Diehl, Moritz (author)Robust and accurate pose estimation of moving systems is a challenging task that is often tackled by combining information from different sensor subsystems in a multi-sensor fusion setup. To obtain robust and accurate estimates, it is crucial to respect the exact time of each measurement. Data fusion is additionally challenged when the...conference paper 2020

Biserkov, Kostadin (author)With the ever-expanding need for accuracy in the world of navigation, Global Navigation Satellite Systems(GNSS) such as GPS and Galileo have become the primary option around the world. As such, the potential damage that can be caused by malicious tampering with the receivers continues to grow. One such threat, known as Spoofing, comprises of...master thesis 2019

Caldera, Ganga (author)After the failure of several large breakwaters in late 1970’s and early 1980’s where the role of rocking and breakage of armour became apparent, the importance of understanding this rocking phenomenon is given a great emphasis. Single layer randomly placed armour units are widely used in breakwater designs as they are more economical due to the...master thesis 2019

de Vries, Maarten (author)Pose estimation through fusion of GNSS with secondary sensors has long been an established field. With the developments surrounding autonomous navigation over the past decade this topic has gained extra importance. In the current literature GNSS based pose and localisation is often improved through fusion with either a IMU}or VS with the goal of...master thesis 2019

Prasanth, Hari (author)In a recent first-in-human clinical study, a therapy based on targeted epidural electrical stimulation together with body weight support has been validated to restore voluntary locomotion in chronically paralyzed subjects with Spinal Cord Injury (SCI). However, the system is currently open-loop controlled, meaning that the stimulation pattern...master thesis 2019

Hidalgo Araya, Marco (author)Deterioration of gait and balance, whether from aging, disease, or injury, has been linked to reduced mobility and increased risk of falling. Wearable sensing technologies, such as inertial measurement units (IMUs), may augment clinical assessments by providing continuous gait and balance data at an increased resolution. The objective of this...master thesis 2018

Masic, Arnela (author)Accessibility of offshore structures is strongly affected by local weather and wave conditions. During rough wave climates, vessel motions prevent people to be transferred safely from and to an offshore structure. To increase accessibility, Ampelmann developed a motion compensating gangway system. The system uses a 6 DoF motion sensor to measure...master thesis 2017

Treffers, Michael (author), Melman, Bart (author)Current trailers and caravans use overrun brakes, which cause overheated brakes in the mountains. A solution is to design an electric brake system in which the brakes are controlled electronically instead of mechanically. The report discusses the control models associated with braking, anti-sway detection and velocity sensor fusion. The RDW...bachelor thesis 2017

Roobeek, M. (author)Injuries are a sportsman’s worst nightmare: They withhold players from playing, they weaken teams and they force clubs to buy a bench-full of substitutes. On top of that, injuries can cause an awful lot of pain. Regulating match and training intensity can drastically decrease the risk of getting injured. Furthermore, it can optimally prepare...master thesis 2017
